The Bunya Pine: A Strange, Impressive, and Useful Tree..

Nuts and Seeds of a Bunya Pine
The cone of a bunya pine contains fifty to a hundred and fifty "nuts", although these don't have the same structure as the nuts of a flowering plant. Each nut is enclosed by a thin covering of tissue, or husk, which can be easily removed. Once this is done, the seed coat or shell of the nut must be opened with a nutcracker or hammer to reveal the large and very tasty seed inside.

I've never tasted a bunya pine seed, but it reportedly has a delicious, nutty flavour. The seeds can be eaten raw but are often boiled—sometimes in brine—or roasted. They are also steamed, fried, and baked. The roasted seeds are said to taste like chestnuts. The seeds are high in carbohydrates and low in fat. A tree doesn't produce seeds until it's fourteen to twenty years old.
